An apartment closed for twelve months, invisible to its neighbors, can suddenly attract the attention of the tax authorities. Vacant properties in major cities no longer slip through the cracks. Even a secondary residence or a property undergoing renovation is not systematically exempt from the tax; the criteria are relentless and often misunderstood.
To identify targeted properties, the administration makes no compromises: it cross-references electricity readings, monitors water consumption, and tracks addresses. Owners are not always informed before action is taken. Mistakes can slip through the cracks, or some cases may warrant an exemption, but one must provide the correct documentation to avoid paying unnecessarily.

The vacant housing tax: why does it exist and who does it really target?
The vacant housing tax acts as a wake-up call for properties that lie dormant in high-demand real estate areas. Where every square meter counts, the state wants to avoid seeing apartments or houses remain unused. This measure targets properties that are supposed to be primary residences but have remained vacant for at least a year. Exceptions are provided for, but they are still limited.
In a large part of the territory, an alternative version exists: the THLV. Applied in non-tight areas when the municipality has decided so, it follows different rules. As a result, in Paris or Marseille, the procedures are not the same as in the suburbs or in a small municipality.

Several criteria must be met before being subject to the tax: the property must be intended for habitation, have been empty for twelve consecutive months as of January 1 of the tax year, lack sufficient furniture for normal occupancy, and be located in a tight area OR not, according to the Insee lists. Some properties escape this rule, particularly in the case of major renovations or reasons entirely beyond the owner’s control.
Before filling out a declaration, it is better to test eligibility for the vacant housing tax. A few minutes are enough to avoid many complications when the time comes, whether during an annual declaration or in the event of a tax audit.
How to check if your property is liable for the TLV?
Criteria to examine as a priority
To determine if your property falls under the TLV (vacant housing tax), the starting point remains the situation as of January 1 of the tax year. If the property has been vacant for a continuous period of one year, without furniture allowing for living, it then falls into the category targeted by the tax. This measure primarily applies to unfurnished residential properties located in a tight area (according to Insee criteria).
To facilitate verification, several criteria must be reviewed:
- The location: only properties located in tight areas are concerned.
- The actual occupancy: less than 90 consecutive days of occupancy per year is enough to validate the vacancy.
- The furniture: the property is not considered occupied if it lacks essential furniture for normal living.
Steps to verify your situation
The tax administration relies on various tools: cross-referencing official data, analyzing previous tax assessments, and inquiries with energy suppliers. In practice, the owner sometimes receives an information letter if the administration believes it has identified a vacant property. To eliminate any ambiguity, there are reliable online simulators and access to one’s personal space on the impots.gouv portal.
It is advisable to keep all usage documentation (invoices, work certificates, various documents). A lack of information or a simple oversight can be enough to trigger taxation under the TLV.

Exemptions, disputes, and precautions to avoid unpleasant surprises
In what cases can one obtain an exemption from the vacant housing tax?
Some situations allow one to escape the vacant housing tax. Among the most common cases, we find:
- The property has been occupied for more than 90 consecutive days during the year.
- Major works have prevented any possible occupancy during the relevant period.
- The vacancy results from a case of force majeure (natural disaster, court decision, etc.).
When a property is vacant for a reason beyond the owner’s control, such as an ongoing sale or searching for a tenant, it is possible to suspend the tax by providing all necessary evidence. It is also worth noting that furnished secondary residences are exempt from the TLV, but they may still be subject to housing tax.
How to contest the vacant housing tax?
An erroneous tax notice can happen. To contest it, the rule is simple: gather all supporting documents (receipts, invoices, various certificates, work reports) and send everything to the public finance center, citing Article 232 of the General Tax Code. The more complete and precise the file, the greater the chances of resolving the situation quickly.
Taking proactive steps to limit risks
Be sure to update the status of the property annually in the dedicated tax space. A change in occupancy, renovations, or any modification can lead to the reclassification of the property as vacant without one realizing it. Using letter templates provided by professionals and supplying clear supporting documents can reduce many complications. A single oversight here can be costly.
The real estate market does not forgive approximation. In cities where demand is soaring, every vacant property becomes a prime target for the administration. It is better to stay vigilant, maintain your evidence, and anticipate, as surprises on the tax notice never wait long.
